Zipped Microsoft EXCEL and ACCESS versions are available in the downloads section. References: Selected references are cited as bracketed numbers. Y'all dating meme. Click here to download the entire reference list in.RTF format. Dating methods are coded as follows: A = Ar-Ar, K = K-Ar, R = Rb-Sr, S = Sm-Nd, U = U-Pb, P = Pb-Pb, M = paleomagnetism, G = geological correlations, b = baddeleyite, p = plagioclase, r= rutile, t = titanite, and z = zircon. Events are rated as A, B and C, where A= confidently linked, B= probably linked, and C= possibly linked – to a mantle plume head. Significant advances have been made to the geology of many regions since this database was published. We offer it here as a preliminary listing of LIPs, regardless of origin. For some events, the volume of magma has also been estimated. Location is given both by country and, in parentheses, by geologic domain.

Large mafic magmatic events at Very poorly dated events in North America, South America, Europe, Asia, Africa, and Australia. This database was originally intended to catalogue extensive mafic igneous events and to evaluate the possible relationship of these events to mantle plumes. The reader is encouraged to consult the original paper for the uncertainty level and other details of any particular age in this table. We are currently working on revisions that will incorporate these advances. Estimates of the areal distribution of each event have large uncertainties and are generally minimum estimates. Events are rated in terms of the likelihood of involvement of a mantle plume head.
